Patent CA-2027384-A1 (CA)
Inventor: RUCKI WILLIAM M
IPC: C08J9/12
Filed: 1990-10-11
Abstract: A foam material dispensing system is provided with a control which measures the amount of high viscosity liquid material delivered to a mixer, determines the amount of pressurized gas required to be injected into the mixer in order to produce a foamable material with a desired gas concentration, measures the amount of gas actually delivered to the mixer, and generates a cumulative error signal representing the difference between the required amount of gas and the gas actually delivered. A control signal is generated to regulate the flow of gas to the mixer in relation to the magnitude of the error signal. A digital flow meter generates a pulse for each incremental amount of liquid material delivered to the mixer during an interval of time. During each successive interval, the pulses are counted and the count is multiplied by a preset gas-to-material ratio, from which the measured gas flow is subtracted and the difference added to the cumulative error term. The error term is combined with a term proportional to the amount of liquid material delivered over a predetermined number of successive time intervals to produce the control signal.

Abstract: The pointer of an air-core meter instrumentation gauge comprises a driven hub via which the pointer is reparably attached to a driving hub on the rotor of the air core meter movement. The driving hub is press-fitted to the rotor in proper circumferential alignment so that when the pointer is attached, the pointer will be inherently properly circumferentially oriented too.  This is accomplished by providing a keyed connection between the driving and driven hubs such that the pointer can be assembled to the driving hub in only one particular circumferential orientation. The hubs also have a snap-together catch feature that is additional to the keyed connection.
